Be it known thet l, 'll iiiuerr PHILLIPS, a. citizen of the limitedftltstes, sud resident of New York, in the county o'iillew York andState of New York, have invented certeiii new and useful improvements inCom biued Phouographic and Clelephonic Apparatus, of which the followingis e specification.

My present invention relates to sound reproducers and more particularlyto uppers tus for use alternatively as e phouogrsh or us on amplifyingtelephone receiver, t .ie latter eplicution more especially for amateurradio purposes.

it is an object of the invention to provide an apparatus of the abovetype which shell elimi e the need for mounting or dismouuting thephonograph sound box or the telephone receiver with respect to the tonearm in order to change over from phonograph to radio operation uiidviceverse, and which shall yet be capable of use at will, either as ephonograph operated by a record, or as on amplifyingtelephone receiveror loud speaker operable from a radio receiving set. It is anotherobject to provide an apparatus of the above type, the operation of whichwill he szirtis'lactoii'y either as u phonographor us an amplifyingtelephone receiver, and which may moreover be employed to pr0- ducenovel efi'ects for simultaneous .reproduction of phonograph records,synchronized if desired with complementary tclephonically transmittedmessages or selections.

The invention has a preferred application to the substantiallyconventional phonograph, the tone arm only of which is moditied toprovide it double inlet at one of which is connected the usual sound boxhaving a diaphragm actuated from the usual stylus, and to the other oilwhich is attached a telephone receiver. In the preferred embodimenttheentire weight of the tone arm together with that of the sound box and ofthe telephone receiver carried thereon, is supported at the pivoted oramplifier end, so that the weight of the telephone receiver which. maybe permanently retained on the tone arm shall not increase the pressureof the sound bur: stylus upon the record groove.

In the preferred application the tone arm inlet or nipple for thetelephone receiver extends horizontally in axial alignment with theletersl offset or nipple for the sound Serial No. $74,615.

plicatiousp in the accompanying drzrwings in which are shown one or moreof various possible embodiments of the several features of thisinvention, v

Fig. 1 is a fragmentury elevation partly in. section of a preferredembodiment of the iii-- ventiori.

Similar reference characters refer to sine ilsr parts throughout theseveral views oi the drawings.

Referring now to the drawings, I here sho'wu a phonograph cabinet 10,supporting apl'ionogreph record turn table 11 to he rotuted by the usualspring or electric motor (not shown) mounted on the lower surface ofmotor board 12. Within the cabinet, is the usual amplifier. 13, to theupper end of which is connected the tone arm 1% In the preferredembodiment, the tone arm is pivotully mounted upon a metal supportspider 15 secured as by screws 16 to themotor board 12, The spider 15has s thrust hearing 17 for e cooperating/thrust Toeermg member 18 atthe lower surface of a spider 19 in the tone arm. A pin 20longitudinallythrough spider 19 End secured thereinto, has a bearing ina corresponding elongated hub 21 in the supports spiderlo andcoustitutes the pivot mount, which permits the rotary movement of thetone arm across the turn table for playing a record. tone arm isillustrutively shown of the taper form, the amplifier end of whichtelescopes into the hub 22 of support spider 15 with The "ill

In the referred en'iboslimont the usual ions arm (inscribed is cast withan integral inloit. or niyoplo 30 axially aligned with inlet or ni aplo24:, and extonrling diametrically opposiio liicroto, and serving as a.mounl for a telephone; receiver of suitable construc" tion.

Moroovr thelikelihood of mislnying or injuring; the separated Sound box. orreceiver, or of scratching furnimm themwith, is wholly obviated in mycmisti-m-tion, in which there no occasion to remove from the tone armeither. the sound l2OX or. the telephone receiver.

T he apparatus is usd as a phonograph in-tlie ordinary manner, it lioingnoicd that since the entire weight of the tone arm and associatedapparatus is supported 5's the thrust bearing 17, the Weight of? thelclc-j phone receiver at the outer end of lilo tone arm will not add tothe pressure of the stylus EZQ'ngninst the record R, The telepllonareceiver casing 31 moreover affords :1 con vcnicnt liandlo foruaanipuloting tho tone arm in starting o. record. Vv'hon ilie recordselection is completed the sound-box may be thrown liacl: to inoperativeposition by pivoting about its mounl '26 urrtlioui; intorferoneswith motelephone receivoi: 31.

To employ the apparatus as a mdio loud 1 box and telephone receiver thequality and 'clearncss of the operation 13 distinctly m1- PIOVBd,both-in phonograph 31nd in radio loud speaker operation. It seemsprobable that in the operation as a phonograph some; of the vibrationsfrom the diaphragm 28 are transmitted through the connecting air columnto the nmgnetic diaphragm 34 and that in the operation as a radioreceiver, vibi'p 'tion in'ipressod on the magnetic diaphragm 3% aresimilarly transmitted to the souk ml box diaphragm. It would appear thatin each case the (linphrn m upon which the vi ln'ations areimpressewould induce in the other diaphragm vibrations in synchronism orsubstanlially in synolironism therewith, oncl that; liis causes the'znelloweal or enrioliod lone quality noted.

My. apparatus is also susceptible of a use which I nclieve is broadlynew, for conjoint memes phonograph in synchronism with the corresponding musical accompaniment played on the record.

lily invention is also an instrumentality tor a distinctly-novelentertainment. A. phonograph musical record Without vocal accompanimentmay be played, for instance, and thereupon the entertainer may play thesame record which now appears to-include a vocal. accompaniment, thelatter produced.

by an assistant in an adjoining room who now sings the accompanimentinto a telephone transmitter -wh1ch is connected 1n a wired telephonecircuit with the receiver 31 on the telephone.

Other interesting, surprising or ludicrous effects may be produced inmanners appan ent from the foregoing.

It will thus be seen that-there is herein described apparatus in whichthe several features of this invention are embodied, and which apparatusin its action attains the various objects of the invention and is wellsuited to meet the requ'iremei'its'ot practical I As many changes couldhe made in the above construction and many apparently Widely diiferentembodiments of this inven tion could be made Without departing from thescope thereof, it is intended that all,

matter contained in the alcove description or shown in the accompanyingdrawing shall be interpreted as illustrative and not in a limited sense.

.Having thus described myin vention, what I claim is new and desire tosecure by Letter-s Patent is In a tone arm, for a combined phonographand radio receiving apparatus, in combinw tlOIhfl. pair of support tubesextending in agrial alignment horizontally from opposite sides of theouter end of said tone arm a sound ,box neck attached to one of saidtubes and a telephone receiver having a cap with an integral hub intelescoping relation. with the other said tube.
